ANTIFREEZING SYSTEM' FOK AUToMoBILE-RA'nI'AToRs.

To all 'whom it may concern: Be it known that I, WTLLIAM-B. DAY,

a citizen of the United States, residing at.

Richmond, in the county of Madison and State of Kentucky, have invented a new and useful Antifreezing System for Automobile-Radiators, of which thefollowing is a specification.

i This invention relates toan anti-freezing system for automobile radiators, one'ofits objects being to provide a tank for rece1v1ng the Water from the radiator when the automobile is left standing in freezingweather,

means being provided whereby, when the engine is set in motion, the water will be ele'- vated from the tank and directed back intothe radiator and `permitted to circulate ini the usual" manner. A Y

Another object is to provide a system of this character which can be installed readily and will be inconspicuous. q

With the foregoing and other objects 1n view which will appearv as the description proceeds, the'invention consists of certain 'novel details of 4construction and combinations of parts which vwill be hereinafter more fully described and pointed out in theclaims, it being understood that various changes may be made in the' constructmn of the parts. without departin A spirit or sacrificing an of the a vantages of the invention as s et orthin the appended claims.

In the accompanying drawings the pre ferred forms of the invention have been shown.

In said drawin Figure l is a side elevation ofthe system constituting. the present invention.

Fig. 2 is a view showing partly in diagram and partly in section the valve and its connections.

Fig. 3 is a View vpartly in section and partly in elevation of a modified form of the lnvention.

Referring to the figures by characters of reference, 1 designates the radiator and 2 the motor of any automobile. Extending downwardly from the bottom of the radiator is a pipe 3 which opens intoa valve casing 4;. A valve 5 is mounted for rotation in the casing and has a straight passageA 6 extending therethrough and another passage 7 therein, the two passages being side by side but out of communication with each other the rod being from the Specification of 'Letters Patent. Patented De, 23 1919,` Application med July 1o, 191s. serial No. 244,30;e

and the passage 7 being so extended asto open through the-'periphery ofthe valve at. .points-ninety degrees apart.y When the passage 6 is in register with the pipe 3 it also communicates with aport 8 in the casing 4, there being a' pipe 9 leading from' this port to a tank 10 which can be suspended at 4 pipe let'leads fromthe port" 1l to thetop.

of the radiator l 'pipe- The valve can be rotated 4in any manner desired, as by means of a rod 15, one end of connected to an arm extending radially rom one end of thevalve while the other end of the r'od is connected to a foot plate, knob, OrI-the like, shown at 16. The arm of the valve has been shown at 17.

and constitutes an' overflow The valve casing 4.- has a vent opening 18 -v spaced-ninety degreesfrom the port '11. It

is to be understood that the top of the .radiator is' to vbe sealed.

Under 'ordina conditionsthe valve 5 turned so that At 'e assage 7 connects the ports 11 and 19, sai nection between the pi es 3 and 9. When it is designed to leave t e automobile stand-v ing where the water in the radiator is likel to reeze',' the valve 5 is turned through ninety deggees.- This will place the orts- 11 and 12 in commuication through t e passage 7 and will alsofplace the plipes 3 and 9 in communication, as shown in 'g. 2. The tank 10 has had the air previously' with drawn therefrom as hereinafter described and, conse uently, .as soon as. the. valve is turned. to t e positlonshown inFig. 2, the water in the radiator will draminto the tank 10. Bv making walls spaced apart 1n the samemanner as a thermos container the water will not freeze within the t When the automobile is to be used and it is desired to'. start the circulation of the water through the radiator, the valve 5 is left in the position shown in Fig. 2 and the engine is started. This will cause a suction to be se't up through the pipes 13 and'let and as4 air is withdrawn valve closing the con' l the tank with double o from the top of the radiator, water will be drawn into the bottom of the radiator through the pipes 9 and 3. As sooni as the radiator has been filled the valve is vshifted 'to its first described position with the'ports 11 and 19 in communication an -the pipe 3 closed. This will leave a partial vacuum within the tank 10. Instead of utilizing theisuction of the engine as the means for controllin the f iow of the water to the radiator, a mo ified sys-v tem, such as shown in -Fig. 3 Ymay be em-V Bloyed. In this :system the radiator 2O as a pipe' 21 extending fromthe bottom! thereof-to a pump 22 driven -by the motor and the tank 23 1s connected to 'the pump bya pipe 24.l The pump is of the usual type .for setting up a .forced circulation. Another pipe connects the top of thetank 23 with the lower portion ofthe jacket of the engine and this pipe 25 has a branch' 26 leading tothe dash 27 where itis provided withan air valve 28;

Under -ordinary conditions thetank 23 is filled with air and thewater will-not circulate therethrough but will flow as ordinarily through the cooling system. When it is def sired to withdraw the .water from. the radiator and jacket, however, the air valve v28- is opened and the air will thus escape from the tank and permit the water to gravitateto the tank. -By opening the top of,the' radiator and operating the pump 21 the water- Y' will be'elevate'd fromthe tank 23 and -a par- ,tial vacuumf thus established in the tank.

The water will then circulate as ordinarily. Itis -to 'be understood, of course, that the valve 28 is 4to be closed while the water is be- -ingvevated from the tank..

at is claimed is :f-,

1. The combination with the; motor and .radiator of low the vleve of the radlator, means for elemotor vehicle, of 'a tank, be-

v'atin water from the tank and forcing it into tie radiator thereby to create a partial vacuum. in the tank, a pipe -connectlon-between the radiator and tank and including a pump,l `and means for controlling com munication between the radiator and tank.

2. The combination with vthe radiator of a motor vehicle, of a tank, a motor, a valve,

and means for shiftin the valve to one positionto 4admit air tot `e top of the radiator and close communication between the radiator and' tank, and to anotherposition to open ycommunication between the radiator and the tankandconnect the top of 4theradiator to :the intake manifold of the motor.

In testimony that I claim the foregoing as my own, I havehereto aixed my slgnature in the presence of two witnesses.
